SUMMARY: Afforestation of the Karst in Croatia started as for back as the
last century. May 7th, 1878, is considered to be the beginning of the organized
word on afforestation of the Karst in Croatia when the »Inspectorate for Afforestation
of the Karst« was funded in Senj. Thus, Croatia has a long tradition
of 117 years in the afforesation of the Karstrocky ground. After this conturylong
period, Croatia is still far from having the Karst area afforested, and
nowdays we can say that Croatia is still at the start of the battle with the Karst
wasteland. Multiple reasons, explaining this situation, exist. During ist long
history Croatia predominantly was under foreign administration, and although
favourable Acts on afforestation of the Karst rocky ground were passed,
the application of the Acts in practice was met with difficulties. Apart from the
aformentioned, during some twenty years in the recent past, forest fires have
unmercifully devestated the forest vegetation and newly-planted pine plantations.
A particular emphasis should be placed on the fact that since 1990, the
year of Serbo-Chetniks aggression on Croatia, the objects of their intentional
destruction were also the forests and forest plantations, thus, makong the present
state of the forester the Karst much worse than it had been prior to the
Serbo-Chetnik´s aggression. Wider regions of Dubrovnik, Šibenik and Zadar
have suffered particularly heavy damage.

Unfortunately, it has to be said that the results of the afforestation activities
on the Karst are very small. On the other hand, if we analyse the forestry
profession and the archieved degree of afforestation techniques it can be said
that the most up-to-date work methods were applied in practice, and that a
remakable success in the plant survial was achived, reaching over 90% m, if
not to say 100%, at times.

Three methods of soil preparation for afforestation were applied by the

— Afforestation by planting and pickaxe, cat in plating
— Afforestation by planting into holes by STIHL 08
— Afforestation by planting on soil undermined by ripper.
On the soil undermined by the ripper the following species were planted:
Aleppo Pine (Pinus halepensis Mill.), Austrian Pine (Pinus nigra Arn.) and
Maritime Pine (Pinus pinaster Ait.). On the terrains of the Forest Districts of
Zadar and Šibenik the one-year plants of Aleppo Pine were planted, and in the
area of the Forest District of Split the one-year plants of Austrian Pine and
Martime Pine, were planted.
The Aleppo Pine seedlings in the area of the Forest District of Zadar were
cultivated in polyethylene pipes, 6 cm. in diameter and 28 cm. in height. Seedlings
for the area of the Forest District of Šibenik and the Forest District of
Split were cultivated in the »Bosnaplast« container, 12 cm in depth.
In all the experimental plots the heights of plants were measured at the end
of vegetational period in centimeters, and the mortality of the planted seedlings
was registered at the same time. The results of the research are presented in
the GRAPHS 1-16.
The best survival results of the planted seedlings for all three species were
displayed by the method of soil undermined by the reppier.
In the area of the Forest District of Split and its sub-Mediterranean part, at
approximately 600 m above sea level, comparison of results was carried out
for all three methods of soil preparation for the afforestation with the Austrian
Pine and the Maritime Pine, and these results are shown in the GRAPHS 5-16.
